Old termite mounds help support high insect biodiversity in tropical rainforests

Imagine wandering through the lush Bornean rainforest, past towering trees and vibrant foliage. You might not give a second thought to termite mounds scattered across the forest floor. But what if we told you these seemingly unassuming structures are bustling metropolises for insects, even long after their original inhabitants have moved on?
That's precisely what a new study, co-authored by Dr Tom Fayle, has revealed! Published in Soil Ecology Letters, the research uncovered that abandoned termite mounds are critical microhabitats, teeming with diverse insect life, particularly ants, in both untouched and previously logged rainforests.
Dr Fayle, Dr Kalsum M. Yusah of the Royal Botanic Gardens, Kew, and Dr Jiří Tůma of the Biology Centre of the Czech Academy of Sciences, discovered that these unoccupied mounds can host five to nine times more invertebrates than the surrounding soil. This means hundreds of thousands of insects per hectare are finding refuge and thriving in these 'ghost towns' of the termite world! This incredible finding challenges our understanding of rainforest biodiversity and highlights the often-overlooked role of "ecosystem engineers" like termites.
